The vc04_services is missing several drivers.  It's in the TODO that we
need to merge them.  I don't understand why this hasn't happened yet.
The entire point of staging is that we merge low quality code as-is so
people can clean it up.

The vchi_msg_queue() function is only used by the out of tree drivers.
The correct thing to do normally would be just to delete it.  The cover
letter says we delete it, but actually we just make it static and add
several more unused functions.

I hate that we're mixing __user and kernel pointers and hiding stuff
as void pointers.  But I can't really review it because it's all out of
tree.

Let's first merge the out of tree drivers or let's delete the staging
code but it's useless to only merge half.
